Application led October 14, 1918. Serial No.

To all'witom it mag/concern Be Vit :known that I, ROBERT T. MnYnR, a citizen of the United States, residing atCanton, in the county of Starkand State of Ghio, have invented a new and useful Sepa'- rator., yof which the following isa specification. f This :invention relates to separators of the air suction type, lthe object vloeing to `construct aiseparator -o this character with means for Ldelivering thel matter to ybe sepa rated toa point ywithin .the separating cyhnder where the maximum edect of the `air current drawn throughvthe particles to be separated can be secured.

Another object is yto construct a separator of this class with means for keeping the matter to be separated ina thorough state of agitation until the separated` particles have reached their respective ydischarge points. f

YVith these objects in view the inventionV consists in the novel construction rand arrangement of parts, hereinafterdescribed, illustrated in the `accompanying drawings, and particularly `pointed out in the appended claims, vit being understood that yarious changes in the form, proportions, sizeand minor details of construction 4may be made within the scope `of the appended claims, without departing from Ithe spirit or sacrifie in Q` lany of the advantages -of the invention.

The frame 1 of my separator is formed ot channel bars `or other suitable material and consists of substantially `a rectangular framework with suitable cross braces and supports `for carrying the separating kmechanism. Mounted upon this frame is a suction 1an 2, of `ordinary construction, which is designed to create a suction within the air .suction compartment 1 through the connecting tube 5, in which is located an air regulater valve 6. Secured to the frame 1 is a bearing 7 and a substantially similar :bearing in which vbearings are revolubly niounted a cylinder 9 Vand ydrive shaft 10. Gears 11 and 12 `carried `by the cylinder 9 are var# .ranged to mesh with smaller gears 14 and 1.5, respectively, vwhich are carried by the shaft 10. one extremity of thel shaft 10 is arranged to mesh with a second'beveled pinion 17 mounted -u-pon 7a drive shaft 18. A pulley .19 .mounted uponthe shaft 18 is driven by a belt 20 leading .toanywell known source of power. kThe rotation of the shaft 18, will, through the meshing of the pinions 16 and 17 drive the .shaftk 10, which in turn through tliemeshing oflthe31gears11 and Maud 12 and l'frotate the cylinder 9.

Extending longitudinally and concentri* cally within the cylinder 9 isa hollow shaft y21 whichis supported by brackets 22 `secured within thecylinder- Aseries of apertures 23 are formed adjacent the lower extremity A beveled pinion 16 secured to ofthe holflowshaft21 and secured in the 'I said lower extremity is asolid rod 24 which is mounted in `bearings similar to the bearings 22.` A feed ypipe 25 extending downwardly from the hopper 26 enters the upper end 'of the tubular shaft 21. valve 27 is located within the feed pipe 25 andfis designedto regulate the flow of material placed in the hopper 26 to the tubular shaft .21. A discharge door 28 is located in the lowermost portion of the vchamber f1.

By the alcove` described arrangement it will be seen that matter to be separated, such for instance as crushed metal ore, when placed in the hopper l26 will feed downwardly through the feed pipe 25 and into the tubular shaft 21. The rotation of the A regulator cylinder 9 vwill obviously rotate the tubular shaft 21 and thus feed the particles of ore oi` other matter downwardly through Said tubular shaft and discharge it through the perforations 23. The suction causedby the fan 2 through the chamber 4 will bedrawn through the lower end of the cylinder 9 thus as the particles lof matter are discharged through the aperture 23 they will be met by the upward air draft passing through the cylinder. The heavier particles of matter, such for instance as the metal within the ore will not be as easily drawn as the lighter particles'such as crushed rock. By the adjustment of the valve 6 in the suction pipe 5 the proper suction can be ore- `ated within the cylinder 9 to influence the the apertures 23will bev-,constantly agitated bythe rotationof the-cylinder and in this connection attention isicalled to Fig. 3 in which the l plurality of small vanes 29 are shown securedl longitudinally ofthe cylinder upon itsinterior. yAs the cylinder revol-ves these van'es will gather'particles of angle.

matter and carry them upwardly until they fall by gravitiy back through the interior of the cylinder. [The lighter material is constantly being thrown into the air current, giving the air a `chance to force it steadily upward, while the heavier particles, not inuenced by theV air :suction will be worked downwardly. In Fig. 4 Il have shown a slight'modification of the above described device infwhich Irun the feed pipe shown at, 30 bent to enter the tubular shaft at an In Fig. 5 I have shown another modification in which the tubular shaft is done away with entirely and the feed pipe 31 eX- tends to a point within the revolving cylinderand discharges the matterv tobe separated. In this vtype of separator .it is obvious that the lower'portion of the feed pipe must be bent at an angle of sufficient inclination to insure the'particles Vof matter being discharged into the cylinder. In this form the air suction would have tobe differently.

adjusted to properly separatev the heavier particles from the lighter, since the feed pipe can only vextendinto the revolving cylinder for a short distance. j

y ,In Figs. 6,Y 7 and 8 Ihave shown` still further modified forni in which the tubular shafty shown at 32 will be rotatably mounted within the brackets 34 instead of secured therein as is thecase in the type shown in Fig. '1. In this form the hollow shaft 82 will be held against rotation with the cylinder 35, by a stationary bracket 36 secured to vthe bearingat the upper end of the said cylinder. Since this forni is especially adapted V'for use'with Very fine particles of matter I have designed a plurality of agitat-ors shown at 37, which are in the form of stiffy bristled brushes yextending" longitudinally of the cylinder and which Vare mounted upon arms extending from collars 38, the said collars being V secured to Vthe tubular -shaft by means of'set screws. It will, be seen that as the particlesof matter are discharged through theapertures in thetubular shaft 32, they will be picked up bythe vanes in the revolving cylinder and since thefagitators` 37 are stationary while the cylinder revolves about them the particles vof matter will be brushed from vthe vanes in passing and thus thrown out intoV the air suction.

V In Fig. 9 I have shown a vstill further `'modified form in which I employ a beveledl pinion 40fmounted upon the drive shaft 10 and meshing with a similar beveled pinion 41, which is mounted upon` a stub shaft 42 carried by a bearing supported thereby the 'top of. the air suction compartment." The opposite end of the said stub shaft also carries a pinion 43 Awhich meshes with a similar pinion 44 securedito the tubularshaft 45. It will be seen by this arrangement that the tubular shaft vwithin the cylinder can be made to rotate ata greater or less speed than therotation of the cylinder itself 'or if deioo si'iedzthe pinion 40l can be arranged to drive Y the pinion 41 in the oppositedirection Vthus rotatingjthe' shaft 45 in the opposite direction to the direction of rotation of the cylinrder. In this `form a` great amount Yof agi- "tation cangbe produced thus insuring that the particles of matter will be thoroughly sep-grated.vv

aving fully described my invention what I claim as new and desire to secure by Letters Patent, is:
